Merge planets.
Build your galaxy.
Drop celestial bodies into the bowl and watch same-rank pairs fuse into bigger ones — dust to meteor, planet to star, and when two black holes touch, the Big Bang clears the field. Easy to start, hard to put down.
No accounts. No ads in the current version. Progress lives on your device and in your own iCloud.
One bowl. Eleven ranks. Endless pull.
From cosmic dust to the black hole — every merge feeds your score, your stardust and your galaxy.
Daily challenge, one world, one seed
Every day the whole world plays the exact same sequence of bodies. One free attempt, a global leaderboard, and a streak that grows like a comet — with a weekly freeze so one missed day doesn't erase it.
The Big Bang moment
Merge your way up to two black holes, bring them together, and the screen erupts — clearing the field and topping up your score. The moment every run chases.
Fair play, family friendly
No pay-to-win, ever: a subscriber scores exactly what a free player scores. Mergelaxy+ adds unlimited challenge attempts and covers the whole family through Family Sharing.
Private by design
No accounts, no sign-up, no data collection in the current version. Progress syncs between your devices through your own private iCloud — we can't read it.
Straight from the game.
The menu, a cascade in progress, the Big Bang, the run that ends too soon, and the daily challenge everyone plays on the same field.
